The Okavango Delta is a vast swampland covering over 9,000 square miles of northwestern Botswana. Abundant populations of bird (herons, storks, cranes, pelicans) and animals (elephants, hippos, crocodiles, antelopes) can be found here, along with a high diversity of plants (fan palms, date palms, papyrus, mopane). Moremi Game Reserve is on the eastern edge of the delta, with Chobe National Park stretching off to the north east. The combination of these wilderness areas is what makes northern Botswana one of the best destinations for an African safari. Here it is possible to see a wide variety of habitat, lots of game and have a true wilderness experience.
The Okavango Delta is formed as the Okavango River enters Bostwana from the Caprivi Strip of Namibia. The river arises over 700 miles away on the Banguela Plateau of south-eastern Angola. The Okavango River has no outlet to the sea but instead empties into the sands of the Kalahari Desert. The delta forms as the river slows and spreads out over this vast area. The summer rains that fall in Angola (starting in January) give rise to the flood that will eventually fill the delta region with water. The water that falls in Angola takes about 1 month to reach Botswana. However it takes about another 4 months for the water to move its way through the delta. This is perfect timing. The floods arrive during the winter dry season in Botswana (June-August) providing life-giving water to thirsty animals and people. In recent years the flood has been so strong that rivers which had been dry for decades are now full of water. The Savutei Channel hasn't seen water since the early 1980s but is now flowing. The same for the Thamalakane River that flows near Maun. The Thamalakane is now feeding water into the Boteti River, a bonanza for the wildlife of the Makgadikgadi Pans. Since the Okavango River has no outlet, most of the water is lost by evaporation and transpiration.
